EPECIFIGATION forming part of Letters Patent No. 545,269, dated August27, 1895.

Application filed December 26, 1894. Serial No. 532,929. (No model.)

To aZZ whom it may concern:

Be it known that I, BARZILLIA J. COLLER, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan,haveinvented certain new and useful Improvements in Boilers, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

The invention consists in the peculiar con struction, arrangement, andcombination of the various parts of a boiler for use as a steamgeneratoror a water-heater, and particularly in. the construction of the heatingand circulating tubes, whereby I accomplish a rapid circulation andobtain a maximum efficiency from the heat of the tire; also whereby theboiler is made in like sections, whereby the expense of manufacture islessened, and whereby the size or capacity of the boiler can readily bechanged by adding or removing the desired number of sections of theheatingcoils, and, further, whereby the water-circulating coils andheaders may be thoroughly cleaned without dismantling the boiler, all asmore fully hereinafter described.

In the drawings, Figure 1 is asectional elevation of a boiler embodyingmy invention.

Fig. 2 is a side elevation thereof, showing the casing in section. Fig.2:) the horizontal headers. Fig. 4 is a vertical section on line so soof Fig. 2. Fig. 5 is an enlarged detail section of the end of one of theinclined manifolds.

The boiler is provided with suitable setting is a plan view of andinclosing casing and grates of any known necting-pipes C. These headersare tapped on their upper face to receive the lower end of the risers ornipples I), one for each secthrough the universal manifold H.

tion of the heating-coils. Each heating-coil comprises the parallelmanifolds E and E at top and bottom, which manifolds are inclined fromthe riser D upward toward the other end. These manifolds on their innerfaces are provided with two threaded nipples F, which are connected bythe vertical circulating-pipes G, the whole section being substantiallythe shape of a rhomb or rhomboid, or whatI shall hereinafter call therhombic sections. From the corner diagonally opposite that at which theriser D connects I form the outlet-pipe G, which connects, by means ofthe horizontal section G into the universal header H. The next rhombicsection has its riser D connected to the left-hand header B and itsmanifolds E inclined in the opposite directions from the manifolds E,while its outlet-pipe and connecting-pipes G and G connect into theopposite side of the universal header H. These sections are thusarranged alternately the whole length of the horizontal headers B, or somany of them are arranged thereon as may be desired to make a boiler ofthe necessary capacity. The water circulation, therefore, will be fromthe two horizontal headers upward through the risers D into themanifolds E E distributed across the fire in an upwardly-inclineddirection through these manifolds and vertically through the pipes G tothe upper manifolds, and thence through the connections G G The uppermanifolds E are provided on their upper surfaces with plugs I, oppositeeach of the pipes G, so that by removing the plugs these pipes may bethoroughly cleaned. The inclined headers E E are also provided withplugs J, which may be removed for the same purpose. In using thisconstruction of boiler for a steam-generator I extend the universalheaders H out through the front of the boiler, casing and connected intothe top of the steamdrum K at one side thereof, as shown in Figs. 1 and2, and the lower end of this drum I connect by the pipes L withextensions M of the horizontal headers B. In the connectious between theheaders H and the drum and the extensions M and the drum I place valvesN N, so that if it is desired to use but a single boiler of a batterythe other boilers may be disconnected therefrom by shutting these valveswithout in any way affecting the operation of those remaining.

I deem it especially advantageous to connect the universal headers intothe steamdrum at the top and side, as shown, for the water flowing offfrom those headers into the drum will strike the oppositedownwardly-inclined face a of the drum and be deflected downward intothe water in the drum, preventing its splashing upwardly into the steamand thereby increasing the moisture in the steam. I find that with thisconstruction I maintain the steam much drier, Whereas heretofore thesepipes have been connected into the steam dome in such a manner as tostrike a vertical side and be deflected in all directions.

\Vhat I claim as my invention is-- 1. In a boiler,the combination ofhorizontal headers a series of rhornbic sections connected thereto atone corner each comprising a lower inclined manifold extending over thegrates, a series of vertical pipes extending from the upper facethereof, the series extending across the boiler and an upper manifoldparallel to the lower manifold and into which the vertical pipes lead,substantially as described.

2. In a boiler, the combination of horizontal headers on each side ofthe fire, a series of rhombio sections connected thereto at one corner,alternately to the opposite headers, and each section comprising alowerinclined manifold extending over the fire space, a series ofvertical pipes extending from the upper face thereof, an upper manifoldparallel to the lower manifold into which the vertical pipes lead,outlet pipes from the upper end of the upper manifold, and a universalheader into which said outlet pipes connect.

8. The combination of a multiple of fur naces, independent watercirculating; pipes, or boiiers for each furnace universal headers at thetop of each boiler, a common steam drum into which the headers connect,return connections from the drum to the bottom of each boiler, andvalves in the universal header connections and in the return connectionssubstantially as described.

4. The combination with the boiler comprising the side headers, theuniversal header at the top and connecting circulatingpipes between, ofa steam drum having the downwardly inclined portion a and located at thefront of the boiler, a return connection from the steam drum to the sideheaders, and a connection from the universal header to the steam drumentering; at the top on the plane of and opposite the downwardlyinclinedportion a of said drum, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
